10 Booting the Host from the HP 3PAR StoreServ Storage
HP 3PAR StoreServ Storage Setup Requirements
Booting from the HP 3PAR StoreServ Storage is supported in fabric and direct connect modes.
During the RHEL installation process, you will specify the correct argument that will take into account
multipathing during the installation process.
Make sure you have allocated enough space when creating your virtual volumes to be able to
install your RHEL 6 or RHEL 5 OS.
After creating your first virtual volume, you must export it to your RHEL host as VLUN 0, since RHEL
requires the root/boot volume LUN to be 0 when booting from the SAN.
